GOSIOVA MILOSAVICH, OF ST. PAUL, MINNESOTA.

SEWER-CLEANING DEVICE.

Application filed November 12, 1915.

To all whom it may concern 7 Pt it known that I, GosPovA MILOSAVIGH, a citizen of Servia, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Sewer-Cleaning Devices, of which the following is a specification.

This invention relates to sewer cleaning devices and is adapted for use in cleaning out sewer pipes, water pipes, or pipes of a similar nature, and provides means whereby the length of pipe between manholes may be cleaned out without the necessity of digging up the pipe.

One object of my invention is to provide means, which when rotated and pressed forward, will loosen and dislodge any sediment in the pipe.

Another object of my invention is to provide a jointed extension to the cleaning means so the cleaning means may be extended to any desired length in the pipe.

Another object of my invention is to provide supports for the extension at intervals throughout its length so as to support its weight and keep it substantially in the center of the pipe that is being cleaned.

Another object of my invention is to provide in the support for the extension antifriction bearing devices so the support may be either rotated easily or slid longitudinally back and forth in the pipe.

With these and incidental objects in view, the invention consists of certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawing which accompanies and forms a part of this specification.

Figure l discloses a perspective view of my device in which 1 is a brush with heavy bristles of steel or other suitable material, and which should be approximately the size of the pipe in which it is to be used, Fig. 2 is an end view of my device 'in a section of a sewer pipe, with the brush removed, showing an alternate construction for the supporting members, comprising caster rollers, while Fig. 3 is a similar view 1n which the supporting members are spring mounted balls.

In the center of the brush 1, I provide a square opening in which the squared end of Specification of Letters Patent.

the extension rod 2 is rigidly attached, and the other end of the extension rod which is also squared is rigidly attached to one-half of the coupling 3, the other half being attached in a similar manner to the second extension rod 4, and any number of lengths may be oined together in a similar manner. Supporting the rods 2 and in j ournaled bearings the supports 5 and 6, respectively, are provlded with a pair of rollers 7 and 8 pivoted on pins 9 and 10, respectively, so the brush 1 together with the extension rods 2 and 4 may be readily slipped into the sewer pipe that is to be cleaned and the brush rotated by the hand'wheel 11 which fits on the other squared end of the extension rod 4. By joining a number of similar sections and provlding them with similar bearings an indefinite length of pipe may be readily cleaned in this manner, the sediment being loosened up and pushed out and the remainder, if any, readily flushed out with water when the brush is removed, or during the operation of cleaning.

Alternate construction of supports for extension rods are shown in Figs. 2 and 3, the one disclosed in Fig. 2 consisting of three caster rollers 12 pivotally mounted on the coupling 3, which is similar to the coupling 3 except that it has the caster rollers 12 mounted therein. The construction disclosed in Fig. 3 has a similar coupling 3 in which sleeves 13 are provided to hold the balls 14: in their ball retainers 15, so they will automatically adjust themselves to the size pipe in which thev are used under the influence of spring 16.

While I have described my invention and illustrated it in the drawing in a certain construction and with a certain combination of parts, it is evident that it may be applied in many ways and I do not wish myself to be understood as limiting it to this particular construction or combination of parts, but the invention may be applied in various ways within the scope of the following claims.

Claims:

1. In a sewer cleaning device the combination of a rotatable cleaning means, an extension rod adapted to drive said rotatable cleaning means, multiple extension rods, couplings adapted to be joined with said extension rod driving said rotatable cleaning means and said multiple extension rods, a

support for one of said multiple extension rods, and means for turning said extension rods.

2. In a sewer cleaning-device the combination of a rotatable cleaning means, multiple extension rods, one of which has one end centrally located in said rotatable cleaning means, couplings for joining said extension rods together, a support for one of said extension rods, and means for turning said extension rods, and through the turning of said extension rods turning said rotatable means.

3. In a sewer cleaning device the combination of a rotatable cleaning means, an extension rod, one end of which is centrally located in said rotatable cleaning means, multiple extension rods, couplings adapted to be joined with said extension rod attached to said rotatable cleaning means, a support for one of said multiple extension cm" of this patent mai be obtained for five cents rods, and means for turning said extension rods.

4. In a sewer cleaning device the combination of a brush, an extension rod attached-to 25 said brush and having a half coupling on the other end thereof, means for turning said extension rod, multiple extension rods adapted to be connected between said turning means and said extension rod attached 30 to said brush, supports intermediate of said brush and said turning means having antifriction bearings adapted to ride on the interior of the pipe wherein said device is placed and adapted to be rotatable and slid- 3-5 able in said pipe.
